PASADENA, Calif., June 15 (UPI) -- NASA says data from its Voyager 1 spacecraft show the venerable deep-space explorer has nearly reached the edge of the solar system.
Voyager scientists say the spacecraft, launched in 1977, has encountered a region in space where the intensity of charged particles from beyond the solar system has markedly increased, leading to the historic conclusion humanity's first emissary to interstellar space is about to depart the solar system, NASA's Jet Propulsion Laboratory in Pasadena, Calif., reported Friday.
